Construction method of cable-stayed bridge cable bent tower
The invention relates to the technical field of bridge body construction, and provides a cable-stayed bridge cable tower construction method which comprises the steps that a cable tower lower formwork is erected on a bearing platform of a main pier, and concrete is poured to the position flush with a beam body bottom plate; a cable bent tower lower formwork is used as a support, a cable bent tower middle formwork is installed, and concrete is poured; the lower formwork of the cable bent tower is dismantled, and the lower formwork of the cable bent tower is decomposed into multiple layers of column body formworks; a plurality of layers of column body formworks are installed on the top face of the middle of the poured cable bent tower, and concrete is poured; and based on the multiple layers of column body formworks, a formwork turnover construction method is adopted, and construction is conducted circularly in sequence. After the cable bent tower lower part is constructed by using the cable bent tower lower part template, the cable bent tower lower part template is dismantled, and the cable bent tower lower part template is decomposed to form a plurality of layers of column body templates, so that the templates can be repeatedly used subsequently, corresponding templates are prevented from being customized, the construction cost is reduced, and the construction efficiency is also improved.
本发明涉及桥体施工技术领域，提供一种斜拉桥索塔的施工方法，该斜拉桥索塔的施工方法包括：在主墩的承台上搭设索塔下部模板，并浇注混凝土至与梁体底板平齐位置；利用索塔下部模板作为支撑，安装索塔中部模板，并浇注混凝土；拆除索塔下部模板，将索塔下部模板分解形成多层柱身模板；在已浇注好的索塔中部的顶面安装多层柱身模板，并浇注混凝土；基于多层柱身模板，采用翻模施工方法，依次循环施工。在使用索塔下部模板将索塔下部施工完成后，拆除索塔下部模板，通过将索塔下部模板分解形成多层柱身模板，以便后续对模板的重复使用，避免了定制对应的模板，降低了施工成本，也提高了施工效率。
